针对准中性Vlasov-Poisson系统中多尺度物理参数共存的问题开展研究,采用渐近保持格式推导出与Vlasov方程相耦合的Poisson方程。数值模拟了一维等离子体在真空中的膨胀,比较了渐近保持PIC算法与传统PIC算法模拟结果的异同。结果表明:两种算法在满足多尺度中小尺度量限制的前提下,其结果保持高度一致;且在克服小尺度量束缚时,渐近保持PIC算法依然可以正确地模拟等离子体的物理行为,大大节省了计算时间。

In this work, the effect of nitriding current density on hardness, crystalline phase composition, layer thickness and corrosion rate of AlSl 4340 steel has been studied. X-ray diffraction analysis shows that thin layers formed during nitriding process are constituted of 7-Fe4n for samples processed between 1 and 2.5 mA/cm2. Thickness of nitrided layer increases proportionally to current density （0 μm for 0.5 mA/cm2 to 15 pm for 2.5 mA/cm2）. Plasma nitriding increased the surface hardness from 300 hV50g for untreated sample, to around 800hV5og for nitrided samples at 1 mA/cm2. While the untreated samples exhibited a corrosion rate of 0.153 mm per year, the corrosion performance was improved up to 0.03 mm per year at current densities above 1 mA/cm2, which is about one fifth of the corrosion rate of the untreated sample.

Complement (C) activation-related hypersensitivity reactions (hSRs) represent an unsolved adverse immune effect of many i.v. administered “nanomedicines”, such as liposomal doxorubicin (Doxil/Caelyx). Because these pseudoallergic reactions can be severe or even lethal, it is an important clinical objective to find biomarkers for proneness for C activation by reactogenic nanoparticles that will allow the prediction of in vivo reactions by in vitro assays. With this goal in mind we identified a normal human blood donor who consistently showed high sensitivity to Caelyx-induced C activation in vitro, whose plasma (Caelyx sensitive plasma, CSP) was subjected to proteome profiling with a library of human plasma proteome specific mAbs. The chip (PlasmaScan-380TM) contained 380 non redundant (with respect to epitopes) mAbs. The analysis revealed 8 proteins that were differentially represented in CSP in comparison with Caelyx-insensitive control plasma. These proteins were identified by mass spectrometry and Western blot analyses to represent factor h (decreased in CSP), factor h related protein, serum amyloid P component, fibronectin, complement component C4, Apo B100, prothrombin and alpha-2-hS glycoprotein (all increased in CSP). Some of these protein changes are consistent with proneness for increased C activation, suggesting the potential use of this method in the search for biomarkers for liposome-induced or other types of nanomedicine-induced hSRs.

目的:评价DRG支付方式对宫腔镜手术住院费用及医疗服务质量的效果。方法:收集2021-2022年安徽省某三甲综合医院697例宫腔镜手术病人数据,按付费方式分为DRG组(n=385)和非DRG组(n=312)。采用描述性统计分析、倾向性评分法、秩和检验,平衡病例间混杂因素后,检验DRG组和非DRG组住院费用及医疗服务质量情况。结果:经倾向性匹配后,DRG组与非DRG组宫腔镜手术病人的年龄、婚姻、住院时间、住院次数、手术级别、切口等级、麻醉方式差异均无统计学意义(P>0.05)。2组病人日均费用、自费金额、一般医疗服务费和护理费差异均有统计学意义(P0.05)。结论:DRG对样本医院宫腔镜手术控费作用不明显,对医疗服务质量水平影响亦不显著,医疗机构在费用结构与服务质量方面仍存在优化管理空间,应结合自身运营特点,对相关指标进行实时、针对性的监测与考核,实现医院控费提质“双控制”。
